Parameters:command - a specified system command.envp - array of strings, each element of which has environment variable settings in the format name=value, or null if the subprocess should inherit the environment

Unlike the exit method, this method does not cause shutdown hooks to be started and does not run uninvoked finalizers if finalization-on-exit has been enabled. As a result, the subprocess may inherit additional environment variable settings beyond those in the specified environment. That is the only way to obtain a reference to the Runtime object.
